Re: [Tinycc-devel] tinycc segfault with gnu getline for unknown reason

[Андрей Аладьев]

This issue exists only in 0.9.25 version (http://download.savannah.nongnu.org/releases/tinycc/0.9.25.tar.bz2)

I've installed tcc from git (git://repo.or.cz/tinycc.git) and this bug dissapeared

Thanks!

test.c

#define _GNU_SOURCE

#include <stdio.h>

#include <stdlib.h>

void read_file ( FILE * file ) {

    size_t  len = 0;

    char *  line = NULL;

    ssize_t bytes_read;

    while ( ( bytes_read = getline ( &line, &len, file ) ) != -1 ) {

        printf ( "%s", line );

    }

    free ( line );

}

int main ( void ) {

    FILE *  file;

    file = fopen ( "/etc/fstab", "r" );

    read_file ( file );

    fclose ( file );

    return 0;

}

tcc -run test.c

# /etc/fstab: static file system information.

Segmentation fault

Then swap lines from:

size_t  len = 0;

char *  line = NULL;

to:

char *  line = NULL;

size_t  len = 0;

tcc -run test.c

# /etc/fstab: static file system information.

#

# noatime turns off ...

So this swap fixed the problem. It is real magick
